V_OL	Low-level output voltage	I_OL = 4 mA	4.5		0.17	0.26		0.4		0.33	V
I_I	Input hold current	V_I = V_CC or 0	5.5		±0.1	±100		±1000		±1000	nA
I_CC	Supply current	V_I = V_CC or 0. I_O = 0	5.5			8		160		80	μA
ΔI_CC⁽²⁾	Supply-current change	One input at 0.5 V or 2.4 V, Other inputs at 0 or V_CC	5.5		1.4	2.4		3		2.9	mA
C_i	Input capacitance		4.5 to 5.5		3	10		10		10	pF

(1) V_I = V_IH or V_IL, unless otherwise noted.

(2) This is the increase in supply current for each input that is at one of the specified TTL voltage levels, rather than 0 V or V_CC.
